Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
F04Anomaly in the parameters of the control boardParameters of the PCB (3980I621) incorrectly loaded/corrupted cause control inconsistencies and the boiler triggers F04. Check by entering the parameter menu and reprogram/adjust with a service tool; if the issue persists, re-record or replace the PCB.
F05Anomaly in the parameters of the control boardIncorrect configuration on the PCB (control parameters) can generate F05 in addition to possible fan faults. Check and correct parameters; if it reappears after adjustment and the fan/wiring is ruled out, reprogram or replace the PCB.
F07Anomaly in the parameters of the control boardIncorrect PCB parameters (flue control/pressure switch configuration) may cause the system to detect an invalid state and display F07. Check/adjust parameters from the service menu; if the fault code persists after ruling out the pressure switch and wiring, reprogram or replace the PCB.
A23Anomaly in the parameters of the control boardParameterization error on the PCB (e.g., incorrectly recorded control values) causes lockout A23. Confirm by entering the parameter menu and restore/adjust to correct values; if not resolved, reprogram firmware or replace the PCB.
A24Anomaly in the parameters of the control boardIncorrect/damaged PCB configuration generates lockout A24 due to internal control logic. Verify and correct parameters with the service tool; if it reappears, reprogram or replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference 3980I621 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is an ABM piece (ABM01A).
What is it used for?
The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.
Is the boiler not igniting, locking out, or is the control board unresponsive?
After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
